Hi all,
I've made a sky dome, produces the UV map, however (naturally) when I apply it it maps to the outside of the object. Can anyone tell me how to map onto the inside? Thanks

That's related to the normals of your triangles. Select them all and click "Flip Normals" or the equivalent in your modelling software - this way you can look at the dome from the inside.

I believe tab for edit mode and then W gives you a method to flip the normals.

In 2.6 Flip normals is under the "t" tab (toggle with T). Flip direction. I advise against a skydome though, they produce very bad results on the top of the dome. Hit up cgtextures and grab one of their cube mappable ones.
